Background technology
In recent years, along with the development of society and the raising of living standards of the people, auto trade had obtained great development in China.Automobile pollution particularly private car recoverable amount increases greatly, must cause people to learn the rise of the continuous stream of vehicles.Yet in the process that study is driven; because many students are skilled not enough to the driver behavior of automobile; the operation that mistake in learning the car process, occurs that this will be difficult to be avoided; steering angle is excessive or not enough, thereby causes the emergency situation of various crisis vehicles and personal safety, generally all has been equipped with auxiliary brake now on the instructional car; side clutch; secondary Das Gaspedal and secondary back mirror and secondary loudspeaker etc. except the part motorcoach, all do not dispose secondary steering hardware basically.Though in case of emergency the trainer also can take emergency braking, lean on the method for the bearing circle that directly rotates student's assurance to change travel direction, change but be difficult to that the travel direction of vehicle is made fast speed, reduced the generation that efficiency of teaching also is difficult to avoid simultaneously emergency case.
Though occurred being equipped with the instructional car of secondary steering swivel system at home and abroad, major and minor bearing circle generally connects by Purely mechanical, it as the patent No. 200420052054.4 double steering wheel wheel word, turn when student's steering vehicle and faulty operation to occur and when being about to cause danger, the trainer wants to realize the control to vehicle, must stir shift fork earlier, could control bearing circle then and turn.Defective is an inconvenience when handling, and is difficult to realize in time the effective control to vehicle.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can overcome above-mentioned defective, easy to operate, steering system of instruction car that reliability is high.Its technical scheme is:
Comprise electric boosted main steering swivel system, detect the detecting device of Steering gear angular transposition in the electric boosted main steering swivel system, storage battery, engine speed sensor, car speed sensor and the secondary steering swivel system that is installed in the operator's compartment copilot station, set up the detecting device of Steering gear angular transposition in electronic control unit and the secondary steering swivel system of detection, wherein the signal input part of electronic control unit connects two detecting devices respectively, engine speed sensor and car speed sensor, its mouth connects magnetic clutch and the assist motor in the electric boosted main steering swivel system respectively, magnetic clutch is captiveed joint with the output shaft of assist motor, it is characterized in that: described electronic control unit can determine which bearing circle in the major-minor steering swivel system is in running order, and provide power-assisted for steering swivel system according to the signal control assist motor of detecting device collection, when instructional car student normal running, electronic control unit is only according to the detecting device of Steering gear angular transposition in the main steering swivel system and the signal of engine speed sensor and car speed sensor output, the control assist motor provides power steering, when the instructional car student operated the appearance mistake, electronic control unit was according to the detecting device of Steering gear angular transposition in the main steering swivel system, the detecting device of Steering gear angular transposition in the secondary steering swivel system, and the signal of engine speed sensor and car speed sensor output carries out corresponding computing, control assist motor in judgement back provides power steering.
Described steering system of instruction car, every cover detecting device include engaging tooth wheels and a potentiometric pick-up, and wherein the driving gear suit is fixed on the Steering gear, and the driven gear suit is fixed on the axle of sensor, and sensor is installed in the operator's compartment.
Described steering system of instruction car, every cover detecting device include a suit and are fixed on driving gear and an electromagnetic senser on the Steering gear, and sensor is installed in the operator's compartment.
Described steering system of instruction car, engine speed sensor and car speed sensor are a kind of of electromagnetic type or photo-electric or hall effect type noncontacting proximity sensor.
Described steering system of instruction car, the Steering gear in the secondary steering swivel system is in antifriction-bearing box is fixed on operator's compartment.
Described steering system of instruction car, the speed reduction gearing in the electric boosted main steering swivel system adopts the turbine and worm speed reduction gearing, and turbine is wherein captiveed joint with the Steering gear in the electric boosted main steering swivel system, and its worm screw is captiveed joint with magnetic clutch.
Described steering system of instruction car, the deflector in the electric boosted main steering swivel system are a kind of of rack and pinion steering gear or ball-and-worm steering system or cam-and-lever steering gear.
Its principle of work is: the present invention can determine by electronic control unit which bearing circle is in running order in the major and minor steering swivel system, and provide power-assisted for steering swivel system according to the signal control assist motor of gathering, the trainer just can be sitting on the position of copilot by handling the auxiliary direction dish and can demonstrate the instructional car method of operation equally and finish teaching like this, and maneuver vehicle independently.When student's normal driving, the trainer does not apply moment of torsion to the auxiliary direction dish, the sensor that survey Steering gear angular transposition in the secondary steering swivel system this moment does not have signal output, electronic control unit receives only surveys Steering gear angular-motion transducer in the main steering swivel system, the signal of car speed sensor and engine speed sensor output, carry out corresponding computing by electronic control unit, output control signal corresponding in judgement back is to assist motor, the rotating speed of control assist motor, and send the signal closes magnetic clutch, the rotating speed of assist motor output increases moment of torsion by speed reduction gearing like this, on the Steering gear of torsional interaction in main steering swivel system, realize the wheel flutter servo-steering by deflector, the student is maneuver vehicle independently.When the student operates the appearance mistake, the trainer applies moment of torsion to the auxiliary direction dish, the sensor that survey secondary Steering gear angular transposition this moment has signal output, electronic control unit is according to the master, the signal of each sensor output carries out corresponding computing in the secondary steering swivel system, output control signal corresponding in judgement back is to assist motor, the rotating speed of control assist motor, and send the signal closes magnetic clutch, the rotating speed of assist motor output increases moment of torsion by speed reduction gearing like this, on the Steering gear of torsional interaction in main steering swivel system, realize the wheel flutter servo-steering by deflector, guarantee normal vehicle operation.
The present invention compared with prior art, its advantage is the drawback that the invention solves in following two kinds of instructional cars study: 1. traditional coach's method is that the trainer whenever finishes once teaching and also will get off and student's transposition, could continue teaching, cause unnecessary time waste, lowered efficiency of teaching; 2. the trainer position that is sitting in copilot is to the guidance that exercises supervision of student's driver behavior, when student's operation mistake will be caused danger, the trainer wanted to realize that must visit body earlier to the control of vehicle hits bearing circle that the student handles and avoid the dangerous generation adjustment direction of stopping again.The invention solves above two kinds of drawbacks, not only effectively raise efficiency of teaching, and improved the safety factor of instructional car, reduced risk, pedestrian's on vehicle, occupant and the road etc. safety is also improved a lot.
